iDefense reported an integer overflow vulnerability in the cli_scanpe()
|
|
function when parsing Portable Executable (PE) files packed in the MEW
|
|
format, that could be exploited to cause a heap-based buffer overflow
|
|
(CVE-2007-6335). Toeroek Edwin reported an off-by-one error when
|
|
decompressing MS-ZIP compressed CAB files (CVE-2007-6336). An
|
|
unspecified vulnerability related to the bzip2 decompression algorithm
|
|
has also been discovered (CVE-2007-6337).

|
|
A remote attacker could entice a user or automated system to scan a
|
|
specially crafted file, possibly leading to the execution of arbitrary
|
|
code with the privileges of the user running ClamAV (either a system
|
|
user or the "clamav" user if clamd is compromised).

|
|
There is no known workaround at this time.

<resolution>
|
|
<p>
|
|
All ClamAV users should upgrade to the latest version:

<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.91.2-r1"</code>
